Narcissine is a word that refers to a person's excessive self-love and admiration. Some synonyms for narcissine include egocentric, self-absorbed, self-centered, self-obsessed, vain, conceited, and self-important. These terms indicate a preoccupation with oneself and a disregard for others. A narcissine person may constantly seek validation and attention, often at the expense of others. Their behavior can be frustrating and exhausting to those around them, who may feel overlooked or undervalued. While it's important to have self-confidence and a positive self-image, it's equally important to be aware of one's own behavior and its impact on others.
